To all whom ifimay concern:

Be it known-that 1, WILLIAM B. G001) NIGHT, a citizen of theUnited States, re

siding at Smallett, in, the county of- Douglas and State of Missouri, have invented certain new and useful Improvements in Shovel-AttachingDevices, of Which the following is a specification.

This inventionrelates to certain new and. useful improvements-in shovel; attaching: de vices for plows; cultivators and. like agricultural implements;

The primary objectof the invention isto provide improved means for securely attaching shovels and like earth Working blades of agricultural implementsto" their supporting" standards; and by means" of which attachment or detachment of the shovels-- may he more expeditiously effected Without the need "of" special skill or the use of" tools, such aswrenches or-the like;

Another ObjGCl) 1s to-p-rovide' an attach? ing device of the flbOVP/klfld" WlllCll' is ex tremely simple anddurablein construction and adapted to be manufactured at a" rela-" tively 10W cost.

Other objects will I appear" as the nature of the; invention is-hette-r understood," and the samesconsists in "the, novel *form', combination and" arrangement ofparts' hereinafter more" fully" described, shown in. theaccompanying drawings and claimed;

Referring:more in dtail to" the drawings ,i 5 indicates. the depending supporting-1stantl ard' or 'shankfof aplow or the likeflarrd' 6 indicates the earth workinghlade or sh'oveli which is" secured against the forward? surface ofthefloiver end" of said standard, the' shovel an-d standard having the usu'alrpairsi' of spacedsuperimposed openings 7 and *1 8"; respectively in"which threaded bolts ar'eor H dinarily disposed, nuts being usually threaded-on suchholts againstfthe rear surface of "the-standard"for securin'gfithe shovel l in place? Thisconventional?mannerofat taching the, shovel" is-obj'ectionable fornw. merous reasons, such" asthe need of consumf ing-muchf time in applying erremoving. the

nuts to effect attachment"orremoval of tli'e shovel; especiallywhen the nuts become rusted on thebolts, and" the: need of" a." Wrench foreffecting turning oftl1'e nutsto applyorfrem'ove them. i V

In accordance"Withthe present invention, threadless. bolts 9" are disposed through" the I openings *7 and-8" and-these bolts have" hook; shaped projecting: rearends as" at" 101-" pref erably formedby. notching' the' shanks of the bolts as-"at 11- A plate" 12 "isdispjos'edagainst the rear surface of the standard-15* and-hasa pair of openings l3 througlrwhich the bolts 9' project, wherebytdrrihg-ofthe plate iskpreventedi; A second circular-i plate 144s rotatably'secured'to the waslrer' plate 9 12"asuat 15 so asito hedi'sposed between the bolts 59 wheirthef p l'ate 12is in' position, and? the rotary plate-'l l has opposed j rearwardly; projecting ar'cuate marginal cam ifl'anges" 16L 5 Whose ends: terminate in. spaoedirelation at the" sidesof-tlre opposed notches lT formed? in theedge ofthe plate 14. The flanges "16 aredisp0sed so' thatftheir'canr edges engage v the inner! sides of the hoo-kshaped" ends of bolts vvlren the plate lki's' rotated, Where 1 by the bolts) 9 are drawnrearwardly" through the parts 5, '6 and 12" for forcing the shovel 6 tightl against the standard 5 .po'sedWitlrthe'notches' 17 coincident with the openings 13 ran-- permitting the plate, 12" to' be 1 slid-F on to; the bolts 9 until." dispose-Ch against the --sta-n'dard" 5, whereupon 'theplate 10 le' is turned' asi-a above: setforth." A" reversal of this operation is h a-d' for eflcting" re moval of the shovel, and it is apparent that accomplished cured to the plate 14 for facilitating manual rotation of the latter, and a resilient catch 19 is secured to the plate 14 and adapted to engage ratchet teeth 20 on the rear face of the plate 12 for preventing accidental backward turning of the plate 14 after the latter has been turned for tightly securing the shovel in place. In other words, the tightening of the bolts 9 is effected by turn ing of the plate 14 in one direction, and the catch and teeth permit such turning of plate 14 but prevent accidental turning of the latter in the opposite direction. As shown clearly in' Figure 6, the catch 19 is provided with a pawl 21 at its free end which projects forwardly through an opening 22 in the plate 14 to engage the teeth 20 and the latter are concentric with the pivot of plate 14 as shown in Figure 7.

A cam 23is disposed between the/free end portion of the catch 19 and the plate from one end of the cam 28 for facilitat-- ing manual turning ofthe latter. 7 This lever 25 normally lies against the plate 14 when the cam 23 is disposed to allow the catch to assume its normal position engaging the teeth 20 but when the lever 25 is swung outwardly or rearwardly, the cam 23 flexes the catch rearwardly so that the pawl 21 is re- 12 for permitting turning of parts-14 and 18 relative to plate 12. y The plate 14 may be held to plate 12 in any suitable manner such as by means of the screw vshown.

From the foregoing description itis believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the. art.

Minor changes may be made without departing from the spirit and scope of the lnvention as claimed.

What I claim as new is: r a 1. A device for attaching an earth working blade of an agricultural implement to the forward surface of its supporting stand-- ard wherein the blade and standard have pairs of registerable superimposed bolt-receivlng openings, including a pair ofthreadless bolts adapted tobe disposed in said openings "and having hook-shaped ends, a

washer plate having a pair of openings for ingblade of an agricultural implement to the forward surface of its supporting standard wherein the blade and standard have pairs of registerable superimposed bolt-receiving openings, including a pair of threadless boltsadapted to be disposed in said openings and having hook-shaped ends, a washer plate having a'pair of openings for reception of said bolts and adapted to be disposed against the rear surface of said standard, and a cam element rotatably carried by the washer plate and engageable with the hook shaped ends of the bolts for drawing the latter through the'blade, standard and washer plate so as to force the blade and washer plate tightly against the respective surfaces of the standard when said cam element is turned in one d rection, and manu-' ally releasable means to prevent accidental turning of said cam element in the other direction.

A device for attaching an earth working blade of an agricultural implement to the forward surface of its supporting standard wherein the blade and standard have pairs of registerable superimposed boltrcceiving openings, including a pair of threadless bolts adapted to be disposed in said openings and having hook-shaped ends, a washer plate having a pair of openings for reception of said bolts and adapted to be disposed against the rear surface of said standard, and a cam element rotatably carried by the washer plate and engageable with the hook shaped ends of the bolts for drawing the latter through the blade, standard and washer plate so as to force the blade and washer plate tightly against the respective surfaces of the standard when said cam element is turned inone direction, said last named means including ratchet teeth on the washer plate and a catch carried by the cam element having a pawl normally adapted to engage said ratchet teeth, said cam element having an opening through which said pawl projects. I

6.
